{:title=>"Beschreibung"}	Students are testing different substances for the pH-value. Some students are testing crystal deodorants using a red cabbage indicator and a universal indicator. The universal indicator suggests that the deodorant reacts as an acid, whereas the red cabbage suggests that the deodorant reacts as a base. What is happening here?
